Vehicle Display Control Video Extraction Range Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems fail to notify drivers when the extraction range for video capture reaches the end of the available video, leading to uncertainty about further adjustments or potential device failures.
Innovation Solution
A display control device with an acquirer, receiver, and output unit that acquires video from an imaging device, receives instructions to move the extraction range, and outputs a notification when the range reaches the video's end, using techniques such as reversing direction, changing magnification ratios, or displaying indicators to signal the end of the video.

Engineering Contradiction Analysis
1Ease of operation
If the extraction range is moved by manipulating an input device, then the user can adjust the video extraction range, but when the extraction range reaches the end portion of the video, the system fails to provide feedback causing user confusion
Solution Approach 1:
The patent applies feedback by detecting when the extraction range reaches the end portion of the video and providing notification to the user. The notification unit outputs a signal indicating that the extraction range has reached the video boundary, allowing the user to understand the system state and adjust their manipulation accordingly.
2Reliability
If no notification is provided when extraction range reaches video end, then the system remains simple, but the driver cannot determine if further adjustments are possible or if there is a device failure
Solution Approach 1:
The notification unit provides feedback to the user about the extraction range status. When the range reaches the video end, the system outputs a notification signal, enabling the user to distinguish between normal boundary conditions and potential device failures.
Solution Approach 2:
The system automatically detects and notifies the user when the extraction range reaches the video boundary without requiring additional user actions or complex external monitoring systems.

AI summary
A display control device is installed in a vehicle and causes to display a video of an area around the vehicle from an imaging device to be displayed on a display device. An acquirer acquires a first video serving as a processing target from the imaging device. A receiver receives an instruction to move an extraction range for extracting at least a part of the first video acquired by the acquirer. An output unit outputs a second video extracted in the extraction range moved in accordance with the instruction received by the receiver to the display device. When the extraction range moved in accordance with the instruction received by the receiver reaches an end portion of the first video, the output unit gives a notification indicating the reaching.
